摘要	In order to reduce crosstalk caused by temperature during refractive index and strain testing, the temperature, refractive index and strain response characteristics of fine-core long-period fiber gratings were studied. A long-period fiber grating with a period of 50 m was successfully prepared on a single-mode fiber with a core diameter of 6 m using the femtosecond laser direct writing method. The results show that long-period fiber gratings processed with low laser energy in fine-core fibers have lower temperature sensitivity, and maintain a larger extinction ratio and better spectral quality. The loss peak of this fine-core long-period fiber grating drifts only 1.7 nm in the 20~700 temperature range. The grating is also highly responsive to changes in the refractive index. when ambient refractive index is in the range of 1.4065~1.4265, its sensitivity reaches 882.51 nm/RIU, and its strain sensitivity is 2.2 pm/. This fine-core long-period fiber grating can better reduce crosstalk caused by temperature in the refractive index and strain tests. Copyright 2020 Chinese Optics. All rights reserved.
